1. Nernst, Gibb's relationship to E° and equilibrium. Everything we've learned so far is inter-related.
a. Fill out this concept map to link these things together mathematically:
AG -EG, (prods)-G,(reacts)
AG° = AH° -TAS
AG =
AG°-
NON-STANDARD

E-E,(ox) + E(red)
b. What is the value of AG and Ecen at equilibrium?
c. What are the signs of AG and Ecen when a reaction is spontaneous as written in the forward direction?
d. What are the signs of AG and Ecen when a reaction is NON-spontaneous as written in the forward
direction?
e. What are the signs of AG°, Keo, and Ecel when REACTANTS are favored in a reaction?
f. What are the signs of AG°, Keg, and E°ces when PRODUCTS are favored in a reaction?
AG =-n FE
